      High Performance. Are your 5.0-liter Mustang's old standard spark plugs robbing you of power and fuel efficiency? Then replace them with a set of Pulstar PlasmaCore Spark Plugs. Pulstar Spark Plugs feature plasma-assisted combustion technology to produce a hotter spark ensuring a complete and rapid fuel burn. By installing a set of PlasmaCore Spark Plugs you will see an improvement in horsepower, torque and throttle response, as well as an increase in fuel efficiency and lower emissions. It is recommended to replace your old spark plugs every 30,000 to 45,000 miles as part of your Mustangs routine maintenance.

      Plasma-assisted Combustion. Pulstar PlasmaCore Spark Plugs feature a patented internal capacitor design that was developed with the help of a US Department of Energy laboratory. The internal capacitor allows the spark plug to store and compress more energy prior to its release, when compared to standard spark plugs. This stored energy is released within nanoseconds delivering a 5 megawatt pulse of peak power. This 5mw pulse discharge of energy ionizes a portion of the gaseous air-fuel mixture turning it to plasma which in turn instantly ignites the remaining air-fuel mixture in a cascading effect.

      Nickel-Chromium Alloy Electrode. Most performance spark plugs feature a fine wire electrode made from a precious metal, like platinum or iridium, in order to increase spark creation consistency. However, this consistent spark energy comes with the price of reduced life expectancy. Because of the plasma-forming pulse that ignites the air fuel mixture immediately, Pulstar Spark Plugs can take advantage of a larger center electrode made from an Austenite Nickel-Chromium Alloy (Inconel) that will extend spark plug life.

      Application. This set of eight (8) Pulstar PlasmaCore Spark Plugs are specifically designed as a direct fit replacement for the 1979-1985, 1988-1993 LX/GT and the 1994-1995 GT Mustangs equipped with the 5.0 liter V8.
